a set ofthe pulleys 57 and 59 is placedat each Y sideof the casing so that thecable can-be attached to an anchor Vat either sideof the apparatus. By'attaching` the pulley 59 to the pivoteda'rm 60, thelpulley will adjust` Y, itself during thevmovement ofv the' apparatus Y Y and this also permits the armv and'pulleyrto VDe 'Smile out Of the weygahennortiuse c 'The We bolt feestjes@ .fortissime l andi v I the apparatfusv on a truck `l7`romthe foregoing it will be'rseeiiwthat they Winding ofy thefcable onl l.the` *drumVW-ill canse the Vapparatns1tourbe.movedlrgsidetvisey towardy that side-ofthe mine vto Whilrlthrf be anchored ata point either in frontor in f Vrear ofthe apparatus so as to move the' ap# cable is anchored; desired, the cable can paratus either forwardly or rearwardly, yor

by anclioringth'e cable to a point to one side foi? therear end ofthe apparatus, the rear lend ofthe apparatus can beg' swung ,to one side or ythe other. After theapparatus has beenproperly vpositioned' by the winding of' dihe cable (inthe-drum', the brake istightened ftofprevent yunwinding ofthey drum.

1 A second drum 6l is rotatably ari'angedon a stud 62 connected with an exterior side of theecasing, thisdruin being provided with a handleg whereby it can be turned. A cable Y maybe attached to this drum and anchored ff. leitherin `:liront or inrear of the apparatus so :that by turning the drumbyv hand, the apparatus can be moved "forwardly oi rear- ;wardly without operating tlieinotoi.- This d rcable can kalso be used to prevent movement Vof the `apparatus when the same is inopera-V tion. A iri'ctionplate 64 is' fastenedifto the side of thecasing Yand engages the inner tace oil? thedruin when a vbolt .65, engaging a rthreadedsocket inthe studj62, is turned, a

riction'fmember 66y being caused to engage theoutei' face of the 'drum when this b Olt is tightened. Thuswhen the bolt istightened,

y the drum 61 is clamped against movementy .Y and thus the druin will be `prevented..from

' turning againstthepull-of the cable.

' A leveling pla` e '67 is hinged tothe-bottom ofthe casing at one yside' thereof yand adjacent'y the rear end, thebottonib'e'ingrecessed, as

A holding dog 7 3* is carried by the housing -lz'orlioldingthe racky bar in adjusted position. It issimply necessary to release the holding dog in order lto vpermit the leveling plate tofreturnk to its normal position in the recess. Y This arrange-A ment permits the apparatus to be Aleveled 'when the mine lioo'r is 4not level. As many oliv .theseplates can be provided as are necessary.

An eye 1bolt Mis attached to the rear end of the apparatus sothat a cable ina'y'be'at-l tached thereto and 'attached to an' engine,

After the cut has been'made, theapparatus can be moved rearwardly by attaching the cable 54 to an anchor at the rear of the apparatus and the apparatus is moved `to the vopposite 'side of the mine to make a new cut bypassing the cable over the pulley 59 and anchoringit to k one'side of the apparatus.
